Chapter 3 VXIpc 800 Series Configuration and Installation Table 3-1 lists the factory-default settings and options for the onboard jumpers and switches. Table 3-1.
Chapter 3 VXIpc 800 Series Configuration and Installation Configuring the VXIpc 800 Series This section describes how to configure the following options on the VXIpc-800: • VXIbus Slot 0/Non-Slot 0 • VXIbus CLK10 routing • Trigger input termination • EEPROM • Installed system RAM How to Remove the Metal Enclosure The VXIpc-800 is housed in a metal enclosure comprised of a top and bottom cover to improve EMC performance and to provide easy handling.
Chapter 3 W13 VXIpc 800 Series Configuration and Installation W13 a. Manual Non-Slot 0 Configuration W13 b. Automatic Slot 0 Detection (Default) c. Manual Slot 0 Configuration Figure 3-2. VXIbus Slot Configuration When the VXIpc-800 is installed in Slot 0, it becomes the VXIbus System Controller. In this role, it has VXIbus Data Transfer Bus Arbiter circuitry that accepts bus requests on all four VXIbus request levels, prioritizes the requests, and grants the bus to the highest priority requester.
Chapter 3 VXIpc 800 Series Configuration and Installation Notice that Figure 3-3b also shows switch S5. You must configure these switches as shown when using the corresponding CLK10 source setting of S3. S3 S3 S5 a. CLK10 Generated from Onboard Oscillator (Default) b. CLK10 Generated from SMB Figure 3-3. VXIbus CLK10 Routing The VXIpc-800 can also be configured to drive the external CLK SMB signal from the VXIbus CLK10 signal.
Chapter 3 VXIpc 800 Series Configuration and Installation When switch S5 is set so that the VXIpc-800 receives the SMB CLK10 signal, you have the option to add a 50 Ω termination to the signal by setting switch S6. Switch S6 is unused—its setting does not matter— when S5 is configured to drive the external CLK SMB signal. Figure 3-5 shows the settings for switch S6. S6 a. Does Not Terminate CLK10 SMB Input (Default) S6 b. Terminates CLK10 SMB Input Figure 3-5.
Chapter 3 VXIpc 800 Series Configuration and Installation Trigger Input Termination You can use switch S7 to terminate the external trigger input SMB with 50 Ω to ground. Figure 3-7a shows the default setting for a non-terminated trigger input SMB. Use the setting of Figure 3-7b to terminate the trigger input SMB. Switch S7 is located above switches S4, S5, and S6, which have no effect on this configuration. S7 S7 a. Does Not Terminate Trigger Input (Default) b. Terminate Trigger Input Figure 3-7.
Chapter 3 VXIpc 800 Series Configuration and Installation The EEPROM is divided into two halves; one half is factory configured and one half is user configurable. Use switch S9 to control the operation of the EEPROM. The setting of this switch determines whether the VXIpc-800 boots off the factory-configured half or the user-modified settings. This is useful in the event that the user-configured half of the EEPROM becomes corrupted in such a way that the VXIpc-800 boots to an unusable state.
Chapter 3 VXIpc 800 Series Configuration and Installation If this situation occurs after you change the configuration, perform the following steps to reconfigure the VXIpc-800. 1. Turn your computer off. Warning: To protect both yourself and the mainframe from electrical hazards, the mainframe should remain off until you are finished changing the settings on the VXIpc-800 module. 2. Change switch S9 to the OFF position as shown in Figure 3-9b to restore the factory configuration. 3.
Chapter 3 VXIpc 800 Series Configuration and Installation SCSI Termination The VXIpc-800 uses active termination on the SCSI-2 bus. Because the VXIpc-800 is always an end device, you should not need to disable the termination; however, for informational purposes Figure 3-10 shows the jumper settings for both enabled and disabled termination. W1 W1 a. Terminate SCSI Signals (Default) b. Do Not Terminate SCSI Signals Figure 3-10.
Chapter 3 VXIpc 800 Series Configuration and Installation System CMOS The VXIpc-800 contains a backed-up memory used to store BIOS defaults and configuration information. To clear the CMOS contents, simply short the pins of W2 as shown in Figure 3-12b. ! Caution: You should not keep these two pins shorted because the CMOS memory cannot be sustained when the power is turned off if these two pins are shorted. W2 W2 a. Normal Operation (Default) b. Clear CMOS Contents Figure 3-12.
Chapter 3 VXIpc 800 Series Configuration and Installation Ethernet Power-On Defaults The VXIpc-800 Ethernet circuitry loads its power-on settings from an EEPROM. You should not change switch S1 from its default setting; however, the switch setting required to do so is included in Figure 3-14 for informational purposes. S1 S1 a. Ethernet Power-On Defaults Loaded from EEPROM b. Hardwired Ethernet Values Figure 3-14.
Chapter 3 VXIpc 800 Series Configuration and Installation 4. Insert the VXIpc-800 in the slot you have selected by aligning the top and bottom of the module with the card-edge guides inside the mainframe. Slowly push the VXIpc-800 straight into the slot until its plug connectors are resting on the backplane receptacle connectors. Using slow, evenly distributed pressure, press the module straight in until it seats in the expansion slot.
Chapter 4 BIOS This chapter contains information on BIOS, the low-level interface between the hardware and PC software that configures and tests your hardware at boot up. This BIOS (Basic Input Output System) provides an easy-to-use graphical user interface to allow you to configure system aspects according to your needs.

Appendix Modifying and Installing I/O Expansion Boards E This appendix explains how to modify and install an I/O board in the VXIpc 800 Series. Notice that some material is different between the VXIpc-850 and the VXIpc-860. Height of VXIpc-850 Plug-In Boards In general, the VXIpc-850 can accommodate any standard-size PCI card and any XT-height ISA card. The height of an I/O card is measured from the bottom of the bus connector to the top of the board, as shown in Figure E-1. Height (4.2 in.
Appendix E Modifying and Installing I/O Expansion Boards Length of VXIpc-850 Plug-In Boards The VXIpc-850 will accommodate PCI or ISA I/O boards that are up to 4.2 in. high and up to 13.415 in. long when DRAM SIMMs 0.85 in. or shorter are used on the processor board (National Instruments provides 0.85 in. SIMMs). Due to slight variances in I/O board geometries, however, take care in every application to identify possible contact with the SIMMs. The maximum recommended board length is 7.72 in.
Appendix E Modifying and Installing I/O Expansion Boards Length of ISA Plug-In Boards Because ISA boards mount with the components facing away from the CPU card, which contains the processor and system RAM, tall DRAM SIMMs may interfere with the circuit card of the plug-in board. Most SIMM modules are at least 1 in. high and would extend into the ISA circuit card keepout area. Therefore, National Instruments provides SIMMs of 0.85 in. high, and does not recommend the use of cards that are longer than 7.
Appendix E Modifying and Installing I/O Expansion Boards Height of VXIpc-860 Plug-In Boards In general, the VXIpc-860 can accommodate any standard-size PCI card and any XT-height ISA card. The height of an I/O card is measured from the bottom of the bus connector to the top of the board, as shown in Figure E-4. .48 in. Component Height (PCI Component Side) .07 in. Component Height (ISA Solder Side) With .85 in. Tall SIMMs 2.51 in. Height (4.2 in. max) 1.50 in. 4.36 in. Length (8.4 in.
Appendix E Modifying and Installing I/O Expansion Boards Length of VXIpc-860 Plug-In Boards The VXIpc-860 can accommodate PCI or ISA I/O boards that are up to 4.2 in. high and up to 8.4 in. long. When DRAM SIMMs 0.85 in. are used on the processor board, the component-side component height on a PCI I/O board shall be 0.48 in. tall in the area shown in Figure E-4. For the same height DRAM SIMMs, the ISA I/O board solder-side component height shall be 0.07 in. tall in the area shown in Figure E-4.
Appendix E Modifying and Installing I/O Expansion Boards Length of ISA Plug-In Boards Because ISA boards mount with the components facing away from the CPU card, which contains the processor and system RAM, tall DRAM SIMMs may interfere with the circuit card of the plug-in board. Most SIMM modules are at least 1 in. high and would extend into the ISA circuit card. Therefore, National Instruments provides SIMMs of 0.85 in. high to give a clearance of 0.07 in.
Appendix E Modifying and Installing I/O Expansion Boards Installing an I/O Board The following material applies equally to all models in the VXIpc 800 Series. Materials Needed You need the following pieces to install an expansion board in the VXIpc-800: • A user-defined panel is required on the expansion boards based on National Instruments blank PCI or ISA panels.

Appendix F Common Questions This appendix answers common questions you may have when using the VXIpc 800 Series. What do the LEDs on the front of the VXIpc 800 mean? Refer to Appendix C, LED Indicators, for a description of the front panel LEDs. Is something wrong with the VXIpc 800 if the red SYSFAIL and FAILED LEDs stay lit after booting the VXIpc 800? If either the SYSFAIL or FAILED LED remains lit, refer to Appendix C, LED Indicators, for troubleshooting steps.
Appendix F Common Questions If I boot the computer without video, and then plug in the video, why is it in black and white? When the computer first boots, the video chips try to synchronize with the monitor. If the monitor is not there, the video chips cannot synchronize and establish color. You need to have the monitor attached at boot time to get color. I’ve installed the SCSI software.
Appendix F Common Questions What if my keyboard connector does not fit into the keyboard port on the VXIpc 800? You can plug keyboards that have a 6-pin Mini DIN PS/2 type connector directly into the VXIpc 800. You can use the keyboard adapter cable that is included with every VXIpc 800 kit to adapt the larger AT keyboard connector to the 6-pin Mini DIN connector.
Appendix F Common Questions How do I check the configuration of the memory, floppy drive, hard drive, time/date, and so on? You can view these parameters in the BIOS setup. To enter the BIOS setup, reboot the VXIpc 800 and press the key during the memory tests. Refer to Chapter 4, BIOS, for more information. Can I upgrade my VXIpc 800? You can upgrade the modular CPU card to upgrade the processor. Contact National Instruments for information.
